Let's divide 51303645 by 131
Let's see how many times 131 fits into 51303645.

Step 1:
131 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 131

Moving on to step 2:
When dividing 51 by 131, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 131

Advancing to step 3:
131 goes into 513 3 times with a remainder of 120.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 393 from 513 and we're left with 120.
Take the next digit (0) from the dividend and append it to 120, then repeat: 1200 / 131

Advancing to step 4:
The number 131 fits into 1200 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 21 after subtracting 1179 from 1200.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 131

Going ahead to step 5:
When dividing 213 by 131, we get 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
The remainder is 82 after subtracting 131 from 213.
Fetch the next digit (6) from the dividend, attach it to 82 and continue: 826 / 131

On to step 6:
131 can be fit into 826 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 3916.0
If we subtract 786 from 826, we get 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 131

Step 7:
The number 131 fits into 404 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 39163.0
Subtract 393 from 404 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 131

Going ahead to step 8:
131 can be fit into 115 0 times, resulting in a remainder of 115.
Write down 0 as next digit of the result. 
Result so far: 391630.0
If we subtract 0 from 115, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 9:
If we divide 1150 by 131, we get 8 and a remainder of 102.
The next digit of our result is 8. 
Result so far: 391630.8
Deduct 1048 from 1150 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
If we divide 1020 by 131, we get 7 and a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 391630.87
Subtracting 917 from 1020 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
131 can be fit into 1030 7 times, resulting in a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 391630.877
Subtract 917 from 1030 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final result is 391630.877 with a remainder of 0.0113.
